WINDOW LATCH.

l Application sied July 16,

My invention has `for its object the production of a window frame, and relates more particularly to .that class wherein the sash of the window is so constructed thatconvenient access may be had for washing either side of the window pane, or for renewing and replacingva pane of glass, the construction being such ythat the upper and lower sashes ofthe window maybe turned vto hori- Zontal position inside of the room.

I so arrange the pivots that the window sash can swing without interference with the sci'een oi1` storm window, if the latter `he in place, disposing the pivots at the lower corners of the inner face of yeach sash so that the sash may swing without ,striking the screen or storm window, and therefore the latter do not have to be removed.

It is to be noted that there is no bottom strip to the outer sash in which the inner sash is mounted for kl the sash to strike against, but the latter rests directly upon the window sill free to swing when desired.

These and other objects and advantages of the use of my invent-ion will be hereinafter more specifically explained. In the accompanying drawings I have .illustrated what I now consider the preferred form of an embodiment of the essential features ofiny invention and in these drawings Figure 1 is a front elevation, partly in section of a window frame with my improved sash therein,

Figure 2 is a vertical sectional view of the same,

Figure 3 is an enlarged sectional detail of one of the attaching members taken on line 3-3 of Figure 1,

Figure 4. is a plan view of the same,

Figure 5 is a fragmentary detail of the divided upper end of the lower sash of the window,

Figure 6 is a plan view of the locking mechanism appliedto each sash,

Figure 7 is a vertical sectional view of said lock taken on line 7-7 of Figure 1.

Referring to the drawings 8 represents a window frame or casing which may be of the construction now in general use, the outer and inner walls of which are spaced apart to form channels within which the weights 9-9 are hung. These weights are connected by cords to each window sash extending over the pulleys 10--10 supported 1923. serial No. 651,954.

bythe window frame inthe usual and well known manner. .f y

An outer or auxiliary window sash comprising side members 11, and the top 12, is

placed within the inner wall of the window frame 8. Arranged between the tops of the side vinemloers of the outer sash of the lower window is a. transversely extending frame member 14C, which is formed of two pieces, detachably joined together by the screws 15 (Figure 5). j

The upper Vsash frame 16v and the lower sash frame 17 are placed within thea-foresaid louter sashes or frames, the outer sashes or frames being arranged `to slide rup and down within vthe channels in the window frame and supported hy the eounterbalance weights 9 in exactly the same manner as in windows commonly employed. kA pivot latch 18 is provided at each of thelower corners of each sash 16 and 17. Housings 19 are provided on the inside vof the sash frames for these pivot latches. -Extending from the latch, through a slot 20,'is a knob l v21, by meansof which the latch may be moved in either direction, to engage or disengage with a socket provided in the side style of the corresponding outer or auxiliary sash. 1

Extending over the pulleys 10 are the cords 22-22, which` support the weights 9 9 on each side ofl the window. Each window sash 16 and 17 is provided with locking mechanism karranged on each side thereof, which locking mechanism is more clearly shown in Figures 6 and 7 A casing formed by the metal plate 23 is attached to the sash frame at any convenient position.

' A bolt 24 is supported in this casing and is adapted to register with a corresponding socket opening provided in the outer or auxiliary sash of the window.- This bolt is movable transversely by means of the cam 25, which is supported upon a shaft 26, mounted in said plate 23. It will thus be seen that the invention does not relate to the manner of mounting the window sashes in the frame but resides in the provision of an outer or auxiliary sash within which the inner or true window sash is pivotally and removably supported.

A link member 27 is attached to the cam 2'5Kand by the connecting member 28 to the holt 24. A spring 29 has eiiitic'tion with the link 27 and at its oppositeend to any stationary point on the casing 23. A. knob extends through aslot in the easing and has connection with the cani 25. As seen in Figures 6 and T, the cam 25 has notches a and 251 for cooperation with a pin oi' the like 33 relatively fixed as seen in Fig ure 6 to limit the movement of the bolt 24 in both directions. f e The spring holds the bolt in normal position to 'engage the soeket i'n the out'er or Iauxiliary sash. To open the win'd'owsash, :the knob is turned, the latch is moyed backw'ar'dly ont of its soelet, "to permit its disen- "ageinent with the outer sash, and to allow ftlhe window sash to be lowered on the piyots 18, arranged in the lower corners oi A'each outer sash of thet window. Y

A recessed portion 'is provided 'in each of the window 'frames 1l, approximately ,mediate the top and bottom of 'each sash. Secured in this recess is a Afastening inein- 'ber 31, one 1end of which is etta'el'ied t'o the :side oi the 'window traine 11,' the opposite endn being provided with 'a hook or "other engaging means adapted to takeoyer a pin 32, projecting` from the side iofthe window sash, to hold the sash in partially open p0- `siti'on as show-n in dotted lines in Figure 2. The window is thus supported when 1being used for Ventilating purposes` 1t `will be observed that l yhave provided a window which may be placed withinfiany window frame now in common use. When 'adjusted l5 in position, the upper and low'er sashes v`of the window may be operated independently of each other. Then it is desired to wash the 'upper sash of the window, 'the lower sash is pushed upwardly to the top ot' the frame and the upper sash is lowered to the bottom ot the frame, thereby reversing the position oit the upper and lower sashes and making it convenient to turn the upper sash to lilorizon'ti-l 'position while in the lower partof the window frame and easy of access for cleaning purposes.

Iclaiin: y, 1. A window, a window sash slifda'ble therein, and a latch therefor comprising a. rotatable member haying a notch, a bolt, a link 'connection between said member l"and bolt, la "spring 'connected et one end to one of the said links, 'a plate to which all of 'said y'elein'e'nts aire 'aHiXed, `and a pin fixed 4in the said plate and in position t'o engage in said notch. e y Y 2. A window, 'a window 'sah *slidable therein, and a latch therefor, comprising a revoluble member, a bolt, `a link pivotally yConnected to said revolublje member, il, ineinber disposed angularly with relation yto `said link and pivotally Connected therewith 'at one endfan'd at the other e'nd :aiixe'd .to said holt, 4and a spring Connected at olie end Ito a liXed support and at the other end to sid link between the ends ofthe latter. l A i In testimony whereof I have 'signed this specication.
